Oldest Korean text
Are there any Korean text written in Classical Chinese which predates the year 1000? What is the oldest text of Korean history? Is there anything comparable to the Japanese Kojiki in age? I’ve found the Samguk yusa but that is extremely late. KAVEBEAR (talk) 04:38, 23 March 2019 (UTC)


 * The Gwanggaeto Stele? It's just in Chinese though, not Korean written in Chinese characters, if that's what you mean. Adam Bishop (talk) 13:44, 24 March 2019 (UTC)

Stereo recording of Stabat Mater (Pergolesi)
This desk seemed more likely to be familiar with recordings of Pergolesi’s Stabat Mater than the Entertainment desk.

I’m trying to remove the vocals from a recording, so that I and a friend can sing to an instrumental accompaniment (privately). I know how one can usually do this in Audible, but it needs the track to have been recorded in stereo with the audio in the centre? And it doesn’t work with either my Rousset version or my Hogwood version.

Do you happen to know a version (which I would happily buy) that this would work on?

Thanks. 2A02:C7D:A399:8600:A1C2:AA0A:647A:DED2 (talk) 14:35, 23 March 2019 (UTC)
 * Here's one: (CD or download) Don't know how well Audible's  Out Of Phase Stereo isolation would work (I use Audacity). —107.15.157.44 (talk) 20:42, 23 March 2019 (UTC)


 * Youtube search for "Pergolesi stabat mater instrumental" found several versions without vocals. You could also give the vocal remover at phonicmind.com a try. 173.228.123.166 (talk) 20:44, 23 March 2019 (UTC)

Those ‘instrumentals’ are generally midis or piano accompaniments, which make for a very unsatisfying experience, musically. I’ve looked. If you’ve found any that use string instruments, please do let me know (there do seem to be some for Rossini’s Stabat Mater, which affects the results when I search). (And I meant Audacity, haha. I’m typing while tired.) I’ve bought a track from that recording, to try in the morning: I hope it works, because those vocals are really not my preferred style!

I just looked and there are a few there: here is one that points to a registration-only site, and here is one that points to the site of (oddly enough) a vocalist. You could keep checking. I think there are better ways to remove the vocal from a recording now than center channel cancellation. That's what that other site I mentioned claims to do, though I haven't tried it. vocalremover.com is another one. Here is a reddit thread with a link to an arxiv paper and some comments on it, if of interest. The method in the paper was apparently still pretty crude, but it is a few years old, so maybe stuff is better now. I remember an Nvidia press release saying something about it recently but I wasn't able to find it with a quick web search. 173.228.123.166 (talk) 04:22, 24 March 2019 (UTC)
